What Is a Grade Calculator?
A grade calculator is a tool that converts points earned into a percentage and an estimated letter grade. Instead of calculating the percentage manually for every quiz, assignment, test, or exam, you can enter your scores and let the calculator do the math.
Grade Calculators Hub uses a straightforward points-based calculation. The calculator adds the points you earned, adds the points possible, and then calculates your overall percentage from those totals.
This approach is useful when your course is based on points rather than weighted grading categories. If your instructor assigns different weights to exams, homework, quizzes, or other categories, a weighted grade calculator may be more appropriate.
How to Calculate Your Grade
The basic formula for calculating a points-based grade is:
For example, if you earn 42 points out of 50 possible points:
Your percentage would therefore be 84%. The letter grade depends on the grading scale used by your school, college, university, or instructor.
Grade Calculator Examples
Here are several examples showing how points-based grading works.
Example 1: Test Score
A student earns 42 points out of 50.
Using the grading scale on this page, 84% is a B.
Example 2: Final Exam
A student earns 138 points out of 200.
Using the grading scale on this page, 69% is a D.
Example 3: Multiple Assignments
A student earns 18/20, 88/100, and 45/50.
The combined score is approximately 88.82%.

The following grading scale is used by this calculator. Grading policies vary between schools and instructors, so check your syllabus or official grading policy when an exact letter grade matters.
| Percentage | Letter Grade |
|---|---|
| 97–100% | A+ |
| 93–96% | A |
| 90–92% | A− |
| 87–89% | B+ |
| 83–86% | B |

| 60–69% | D |
| Below 60% | F |
Can I Calculate My Current Grade?
Yes. You can enter the assignments that have already been graded and use their points earned and points possible to calculate your current points-based grade.
Leave ungraded assignments out of the calculation because they do not yet have a recorded score. The result represents your performance based on the completed work you enter.
If your instructor uses category weights or gives an upcoming exam a specific percentage of the final course grade, a standard points-based calculation may not represent your official current or projected grade.
Points-Based vs. Weighted Grades
Not every course calculates grades in the same way. A points-based course may treat every point equally, while a weighted course may assign different percentages to different categories.
Points-Based Grading
Uses the total points earned compared with the total points possible.
Points Earned ÷ Points Possible × 100Weighted Grading
Gives categories different importance, such as exams, homework, quizzes, and projects.
Category Scores × Category WeightsIf your course uses weighted categories, use a weighted grade calculator or follow the calculation method provided by your instructor.
How Accurate Is This Grade Calculator?
The arithmetic used by this calculator follows the standard points-based percentage formula. The result depends on the numbers entered and on whether the course actually uses a points-based grading system.
The percentage is calculated from the total points entered. The displayed letter grade is an estimate based on the grading scale shown on this page.
Because grading policies differ between schools, colleges, universities, courses, and instructors, the official grade should always be confirmed using your course syllabus, gradebook, or instructor's grading policy.
Grade Calculators Hub aims to provide straightforward, transparent calculators that show how a result is obtained. We explain the underlying formula and identify assumptions that can affect the result.
Frequently Asked Questions
Can I calculate my grade with multiple assignments?
Yes. Enter each completed assignment with the points earned and points possible. The calculator adds the earned points and possible points before calculating the overall percentage.
This points-based method automatically gives more influence to assignments that are worth more points.
Can I calculate a weighted grade?
Not with this basic points-based calculator. It calculates your grade by comparing total points earned with total points possible.
If your course uses categories such as exams, homework, quizzes, and participation with different percentages, you should use a weighted grade calculation instead.
Does this calculator work with decimal scores?
Yes. You can enter decimal values such as 8.5 points out of 10. The calculator uses the values you enter when calculating your percentage.
What if my points earned are higher than the points possible?
The calculator will display an error because points earned normally should not exceed the maximum points possible for an assignment. Check the numbers you entered and correct any typing errors.
What grade is 90 percent?
Under the grading scale used on this page, 90% is an A−. However, grading scales vary, so your school or instructor may classify 90% differently.
What grade is 80 percent?
Under the grading scale used by this calculator, 80% is a B−. Check your course syllabus for the official grading scale used by your school or instructor.
Can teachers use this grade calculator?
Yes. Teachers, tutors, instructors, and students can use a points-based grade calculator to convert raw scores into percentages and estimated letter grades.
Is this grade calculator free to use?
Yes. This calculator is designed to provide a quick way to calculate a points-based grade without requiring manual calculations.
